Reclaimed ABS flame-retardant modified material and preparation method thereof

Abstract

The invention relates to the technical field of recycling of an ABS reclaimed material, and particularly relates to a reclaimed ABS flame-retardant modified material and a preparation method thereof. The reclaimed ABS flame-retardant modified material comprises the following substances: an ABS recycling material, a composite flame retardant, a flame-retardant synergist, a composite anti-aging agent, an antioxidant, a composite toughening agent and a coupling agent. The reclaimed ABS flame-retardant modified material prepared through the method disclosed by the invention has high flame-retardant grade as high as V-0 grade, is high in ageing resistance through the addition of the composite anti-aging agent, can be used for enhancing the tensile strength and the bending strength through the addition of the toughening agent, has the advantages of high anti-impact strength, good processing flowability, high glossiness of a finished product, stability in thermal deformation property, high char yield after combustion and no melting dropping and is greatly enhanced in flame retardance without being influenced in mechanical property. The preparation method disclosed by the invention has the advantages of high ABS purity, few impurities and simple preparation process of the obtained ABS recycling material and excellent property and easiness for industrialization realization of reclaimed ABS.

Description

technical field [0001] The invention relates to the technical field of recycling ABS regenerated materials, in particular to a regenerated ABS flame-retardant modified material and a preparation method thereof. Background technique [0002] Today, China has entered the peak period of discarding household appliances, and more than 30 million discarded household appliances will be produced every year. Such a huge waste of household appliances will inevitably produce a large amount of waste plastics. There are three ways to recycle waste plastics: sanitary landfill, incineration for heat, and resource recycling. Among them, landfill and incineration are likely to cause waste of resources and secondary pollution, which is contrary to the theme of the era of green environmental protection. [0003] Nowadays, the recycling of waste plastics mainly adopts the method of recycling, mainly including direct regeneration, modified regeneration, gasification and oil treatment. However, ...

Problems solved by technology

However, for recycled ABS materials, its mechanical properties are much lower than those of fresh ABS raw materials. If you want to continue to use ABS recycled materials in electronics, electrical appliances, automobiles and other industries after modification, you must improve their flame retardancy, toughness, etc. Effective modification of impact resistance and impact resistance to meet material performance requirements for different uses
